Last year, the FBI was caught red handed while tracking an California resident without a warrant. Now, an undetermined branch of law enforcement has been caught doing the same, using two trackers on one car.

According to Wired's Threat Level, the San Jose resident referred to as "Greg" first found the first on his Volvo three weeks ago and left it there, uncertain of what to do. After Wired photographed the first device, whatever agency was tracking him came and swapped out the device.

When Wired interviewed Greg a second time, four different cars surfaced over the course of the interview, which was conducted in two locations, though no contact was made.

Greg believes that he's being tracked because of a cousin who was being investigated by the DEA in a drug-related case, and fled to Mexico.

"He took off. I think he was fleeing. I think he committed a crime," Greg told Wired.com, asserting that he himself is not involved in drugs.

Greg says he bought the SUV from his cousin in June, paying cash for it to a family member. He examined the car at the time and found no tracking device on it. A month later, he drove his cousin's wife to Tijuana. Greg says he remained in Mexico a couple of days before returning to the U.S.

Furthermore, Wired found that all the gear being used in tracking Greg can be traced back to manufacturers who primarily deal with government and law enforcement agencies, or have publicly acknowledge having contracts with them.

As Wired points out, this comes at a peculiar time when the U.S. Supreme Court is about to hear a case on whether or not warrantless tracking should be legal. If the Government is allowed to follow someone who is likely only associated to a guilty party, how far can they take this? Will political dissidents be silenced? And will there be any system of accountability for corrupt individuals in these agencies? I'm not one to get overly paranoid, but even I become uneasy at the thought of this all. [Wired]
